Specification of Letters Patent.

Patented Sept. 11, 1906.

Application filed July 24, 1906. Serial No. 327.468.

To all whom it may concern.-

Be it known that I, Gnone LENTSCHAT, a subject of the German Emperor, and a resident of Hohen-schbnhausen, near Berlin, Germany, have invented new and useful Improvements in Distant-Acting Electrical Gas- Igniters, of which the following is a specification.

The present invention relates to the class of distant-acting electrical gas-igniters, specially street-lamps, in which the passages of the pass-valve are alternatively opened or closed by means of a ring which may be rotated by electromagnetic means.

According to my invention I rotate said ring indirectly by means of a gear, although I know that such ring can be directly rotated. The advantages which I hereby attain are to employ a proportionally low electromagnetic force to rotate the said ring, to regulate ad libitum the gas-passages, and to switch a number of gas-flames on one circuit without altering the gas-igniter, so that I can simultaneously ignite several flames and extinguish the same in series.

In the accompanying drawings, in which like characters refer to like parts throughout the different views, I have illustrated my in vention.

Figure 1 shows a longitudinal section through the apparatus with burner. Fig. 2 shows a front view of the armature and its diagram. Fig. 3 shows a cross-section on lines a: y of Fig. 1. Fig. 4 shows a cross-section through the casing on lines a 1), whereby the driving-gears are drawn in a front view. Figs. 5 and 6 show the driving-gears for the simultaneous ignition and serial extinguishing of gas-flames in a position corresponding to the simultaneous ignition and serial extinguishing of the gas-flames. Fig. 7 shows a modified form of the drivinggears.

The cock-valve consists of a stationary ta-' pered cock 1, providing a passage 2, communicating with the gas-feeding pipe, and of a rotary and movable tapered ring 3, which fits the cock 1 gas-tight. A spring 20 serves for a still better fitting of the gas-cock 1 and the covering-ring 3.

The cock 1 is provided with six concentrically-arranged tapered bore-holes '2 and another centrically arranged passage 2", which contains the ignition-pipe branch of the passage 2 of the cock 1. Above the six concentrically-arranged tapered bore-holes are six horizontally-placed radial bore-holes 2 which may communicate with each other by a channel (not shown) and which are in communication with the gas-pipe feeding the burner. The ring 3 is provided with six longitudinal cuttings 3, which if the cock-valve is open serve for a communication between the two series of bore-holes and feed the gas to the burner. The electrical equipment consists of two elcctromagnets 4, with two armaturcs 5. The two armatures 5 have a common axis of motion 6.

The mechanism which transfers the motion of the armature to the ring 3 consists ofgear-whecls 16 17 18 1t) and of a ratchet wheel 13, which advances one tooth at each closing of the current. This advancing motion is caused by the following operation: The magnetic coils 1 take the current, attract the armatures 5, and advance the pawls 9, fastened on the same by screws 10. The front of the pawls is U-shaped, and they carry on their back ends two ratchets 7 and S. if the armature 5 is attracted, the ratchet 7 rotates the ratchet-wheel 13 half a tooth, while the ratchet 8, situated in the middle between two teeth, laps over the next tooth and rotates the ratchet-wheel 13 half a tooth during the armature reaction. The armature reaction is effected by a spring 11, which is fastened with one end on an arm 12 of the pawl 9 and with the other end on a lever 14. The tension of the springs 11 can be regulated by means of lever 11 and set-screws 15.

The motion of the ratchet 7 and S is transmitted to the ring 3 by means of the ratchetwheel 13 and the toothed wheels 16 17 18 19. The first toothed wheel 16 is firmly connected with the ratchet-wheel 13 and rotatable around the prolongation of the cock 1. The toothed wheels 17 and 18 are firmly mounted on a rotary shaft 21. The fourth toothed wheel 19 is firmly mounted on the ring 3 or, as shown in the drawings, a part of the ring itself.

One of the two condnoting-wires of each of the two electromagnets is connected to the casing, while the two other wires of the electromagnets are connected to the two insulated clamps 2'2. nected by metal straps with the screws 23 These clamps 22 are con' and with the working conductor 24, while the terns.) In the mechanisms in which the derivation through the conductor 25.

If the distant-actinggas-igniter is used to ignite or extinguish a number of gas-flames or street-lamps, the gearing, as shown in Fig. 7, must be used. This gearing differs from the one shown in Figs. 5' and 6 in so far as the wheel 18 has been provided with teeth on its full circumference. If now by causing a number of closings of the current the ratchetwheel 13 is rotated, this movement will be equally transmittedto the ring 3 by means of the gearing 16 17 18 19, and consequently the gas-outlets of the cock 1 are closed and opened b means of the ring 3.

If the istant-acting igniter is employed to ignite several gas-flames at the same time, but extinguish said flames at different times, as it is the case with street-lamps with night and day lanterns, it is necessary for the use of the mechanism as above described to apply two separate circuits. In order to prevent this and still to connect all mechanisms up to one circuit, I have constructed the toothed wheel 18 in such a manner that by taking away a part of the teeth a larger space 26 is produced, the size of which is such that at one full revolution of the toothed wheel 18 the bore-holes of the cock 1 will relate in the same position to each other. By this construction it is possible to allow a simultaneous ignition of the gas-flames, while the extinguishing of the same may take place at different times.

the casing connects to The small spaces in the toothed wheel 19- of the ring ,3 and in the toothed wheel 18, which are referred to in the drawings by the numerals 27 and 28, serve for the purpose of overcoming little inaccuracies in the working of the teeth. It is thought that the position of the toothed wheel 18, Fig. 5, is for evening flames, that of Fig. 6 for night flames, both mechanisms being switched on one circuit with closed valve-cocks, this being the case during the day-time. The bore-holes of cock 1 are shown in dotted lines, while the cuttings of the ring are illustrated by full lines.

The operation is as follows: If by a certain number of circuitclosingsfifteen are necessary in the drawn illustrationthe toothed wheels 18 have made one-third of a revolution, they will turn the toothed wheels 19 of the ring 3, Figs. 5 and 6, so that the cuttings of the ring 3 communicate with the boreholes of the cock. The gas can pass to the burner 'and will be ignited by the day flame. Evening and night flames are consequently ignited at the same time. Fifteen more circuit-closings are necessary to turn the ring 3, Fig. 5, far enough to attain the same position as before the ignition of the lanterns. The gas-passages are blocked while all lanterns, the toothed Wheels 18 of which show such ad- 6 5 j ustment, would be blown out, (evening lantoothed wheels 18 are adjusted, as in Fig. 6, it Will be clearly understood that the movements of the armatures do not aflect the position of the ring 3 to the cock, as the large space 26 of the toothed wheel'18 passes the toothed wheel 19 without rotating the same. The lanterns of a city which is switched on such circuit would have its lanterns alight, (night lanterns.) If the circuit is again closed, the large spaces 26 of the toothed wheels 18, adjusted as in Fig. 5, pass the toothed Wheels 19 of the rings 3 without r0- tating the same. Consequently the cockvalves are closed, while the toothed Wheels 19, provided that the toothed wheels 18 are adjusted as in Fig. 6, bring the ring 3 in a position to block the bore-holes and to close the cock. In order to ignite the lanterns in series at different times and to extinguish the same simultaneously, all that is necessary is .to use the same arrangement reversed.
